AIR-PURIFIER FOR REFRIGERATORS.

SPECIFICATION forming part of Letters Patent No. 636,651, dated November 7,1899.

Application fi ed September 26. 1898. Serial No. 691,845. (No model.)

To all whom it may concern: sition. Fig. 3 representsa perspective view Be it known that I, JOHN G. FLEMING, a cititaken from the side opposite to Fig. 2. Fig. zen of the United States, residing in the city 4 represents, on an enlarged scale, a vertical and county of Philadelphia, State of Pennsylsectional view showing the preferred manner 55 5 Vania, have invented-a new and useful Imof securing the screens in position. Fig. 5 provementin Air-Purifiers forRefrigerators, represents a front elevation of Fig. 4, partly &c., which improvement is fully set forth in broken away, showing the manner of securing the following specification and accompanying the inner and outer screens in position. drawings. Similar letters of reference indicate corre- 6o My invention relates to improvements in sponding parts in the figures.

stationary refrigerators intended for family Referring to the drawings, A designates a use and small dealers; and it consists ofa box casing which constitutes a purifier and has a or casing constructed of tin, iron, or other closed rear wall or back B, a closed top wall metal and of triangular or other shape, the O, and closed side walls D, said casing in ver- 65 I same constituting an air-purifier and being tical section being in the present instance of cated in the present instance in the upper cortriangular form. The side of the casing which ners of the refrigerator, said purifier being adfaces the interior of the refrigerator is occujusted or supported in the refrigerator by the pied by a foraminous wall E, consisting of connection of pipes from the exterior leading the diaphragms F, of netting, gauze, screen 20 to the interior thereof. By making the purior open work, or perforated plates, between fier of triangular shape I am enabled to fit which is sustained amass of charcoal or other the same closely to the inner corners of the purifying material, as at G, it being noticed refrigerator and to expose a comparatively that said wall E inclines from the inner end large surface of charcoal or other air-purifyof the top wall 0 of the casing to the bottom z 5 ing material to the interior of the refrigerator, of the vertical wall B thereof, said wall E besaid charcoal being retained between wire ing separated from said wall B, so as to leave screens, while the angular portion of each between them the air-receiving chamber H. purifier can be readily fitted into the corners J designates inlet-pipes which conduct air of the refrigerator. The air-chamber in the into the lower portion of the chamber H of o interior of the purifier communicates with the the purifier, said air being conducted thereexterior of the refrigerator bymeahs of a plufrom through the pipe J, whereby it will be rality of pipes or conduits, one of which conseen that a body of pure air is always conducts air from the exterior to the surface of tained within the purifier in the air-chamber the charcoal on the inside of the purifier, said H, whereby the charcoal is kept in a perfect 5 air being afterward discharged from the upand healthy condition, it being further apper portion of said purifier, whereby the charparent that said charcoal or other purifying coal is kept in a healthy condition without material between the foraminous diaphragms permitting'any of the external air to enter the F will effectually absorb and neutralize the interior of the refrigerator, which latter. acnoxious gases which may exist within the re- 0 0 tion would raise the temperature and destroy frigerator. It will also be seen that the pipes the advantageous results sought to be at- J and J are adapted to support the casing tained. and attachments within the refrigerator, the My invention further consists in novel dewalls of the latter having formed in them tails of construction, all as will be hereinafter simply openings to receive said pipes, whose 5 fully set forth, and particularly pointed out inner ends are connected with the walls B in the claims that follow the specification. and their outer ends communicate with the Figure 1 representsa vertical section of an atmosphere, so that the device is applicable air-purifier embodying my invention and a to refrigerators in use as already constructed refrigerator to which the same is applicable. without necessarily constructing new refrig- I00 50 Fig. 2 represents a perspective View, in Vertierators therefor.

cal section, of the air-purifier in detached po- In order to connect the foraminous diaphragms with the walls of the casin g A, said walls are formed with lips K and L to engage the ends of said diaphragms, the same being secured to said lips by screws or rivets, whereby the charcoal can be effectively supported between said diaphragms.

In practice I make the wire screen next to the charcoal on either side of fine wire, and next to the latter I place screens of coarser wire, the latter serving to support and give strength to said fine wire.

It will be evident that other fastening devices'or means may be employed for securing the wire screens in position, and I do not therefore desire to be limited in every instance to the exact construction I have her in shown and described.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is

1. In an air-purifier, a casing having an outer closed top, rear wall, and sides and internal screens having charcoal therebctw'een joining said top, sides and the lower portion of said casing, in combination with an airchainber located in the space between the rear of said screens, and said rear wall and top.

2. An air-purifier for a refrigerator consisting of a casing having a closed top, sides and back, said sides being narrowest at their lower portions, and an inclined wall common to said top, side and back and formed of f0- raminous diaphragms having between them purifying material.

3. An air-purifier for a refrigerator consisting of a casing having a closed top, sides and back, and an inner inclined wall formed of foraminous diaphragms having between them purifying material, said casing having between its outer and inner walls an airchamber which is in communication with the atmosphere through the air-conducting pipe, and with the interior of the body of the refrigerator through said diaphragms and material.

4. In an air-purifier for a refrigerator, a

casing having a top wall and an inclined wall formed of foraminous diaphragms, purifying material between said diaphragms, and the top wall of said casing being provided with lips which are engaged by the upper ends of said diaphragms, the lower ends of the latter being secured to the lower portion of said casing.

5. In an air-purifier, a closed casing having foraminous walls, an air-chamber formed between said casing and one of said walls, charcoal supported between the latter, and inlet and outlet pipes extending from said casing and communicating with said air-chamber, said pipes being adapted to support said casing and its adjuncts.

(3. In an air-purifier, a triangular-shaped casing having its longest side composed of screens having charcoal therebetween, an airchamber formed between said charcoal and the angular portion of said casing-and inlet and outlet pipes for said chamber, said pipes serving as a support for said casing.

7. An angular-shaped casing,a wall of charcoal bridging the space between the top and sides of said casing,a fine-wire screen on either side of said charcoal, coarse-wire screens adjacent each fine-wire screen, an air-chamber located between said Wall of charcoal and the angular portion of said casing and inlet and outlet pipes for said air-chamber.

S. In an air-purifier, the combination of a refrigerator, a casing located within the latter and having foraminous walls, an airchamber formed between said casing and one of said walls, charcoal supported between the latter, and inlet and outlet pipes extending from said casing through the sides of said refrigerator and communicating with said airchamber, said pipes serving to support said casing within said refrigerator.
